Hi there dg enthusiasts,
Hope everyone’s doing well, I have been away from this site for a while, but hope to get back to it in the new year. Just did a massive cleanout of comment spam (18,000 spam comments!) and installed a spam blocker to prevent this from happening again.
Hope to add some additional documentation and information in the next couple of months.
I just posted the mac and windows binaries for dgemu, my digital group emulator.
As soon as I have a chance to clean up the source code a bit, I will release that as well. Also will most likely build a linux version as well.
dgemu emulates a dg system with a Z80 processor card, 64k of memory, a 64 or 32 column TV card, cassette interface, and ASCII keyboard.
I used Marat Fayzullin’s excellent Z80 emulator code for the Z80 processor core.
Software is loaded from tape images which I converted from audio files from Bryan Blackburn’s bytecollector site, using a suding format conversion program which I will also release shortly.
Please try out the emulator for yourself and feel free to contact me with any questions. There is no speed regulator on dgemu right now so some of the programs run ridiculously fast (especially Lunar Lander!) but that will be fixed soon.
Please keep in mind that this is a work in progress. More updates to follow shortly..
Hi everyone. Welcome to thedigitalgroup.org. This site will be dedicated to preserving information about the computers produced by the digital group from 1975-1979. I will do my best to provide information, links, and original documentation for the machines, as well as some exciting modern developments.
My first announcement is a cross-platform dg emulator, which emulates a Z80 based dg system with cassette storage. I will be posting Mac, Linux, and Windows executables soon, as well as source code as soon as it is cleaned up a bit. Thanks for reading and hope you will visit again soon.
